RUDDER HOLDER AND SUPPORT.

fiPEC'IPICATION forming part of Letters Patent No. 299,265, dated May 27, 1884.

Application filed February 20, 1884.

To all whom it may concern Be it known that I, CHARLES A. BrennansoN, of Alpe'na, in the county of Alpena and State of Michigan, have invented a new and Improved Rudder Holder and Support, of which the following is a full, clear, and exact description;

The object of my invention is to provide a simple, inexpensive, and durable holder and support for fitting the rudder to a ship or boat. The invention consists in a bed-plate fixed to the vessel and a collar fixed on the rudder post, said bed-plate and collar being tongued and grooved together to insure a firm hold of the rudder to its place, and permit easy movement of the rudder in steering the vessel, and whereby also the rudder-post and its casing are protected from wear, and leakage around the post is prevented. and the lower bearingshoe of the rudder is or may be relieved of downward strain by the weight of the rudder all ashereinafter fully described and claimed. Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate .corresponding parts in all the figures.

Figure l is a sectional side elevation of part of the stern of aship or boat with myimproved rudder holder and support shown as applied to use. Fig. 2 is an enlarged plan view of the holder and support, with the rudder post clamp-ring partly broken away; and Fig. 3 is a sectional elevation 011 the line a- :0, Fig. 2, and with the rudder-post shown in part and in dotted lines.

My improved holder and support need c011- sist of but few parts, a base or bed plate, A, having a flange, a, through holes a of which any suitable bolt or other fastenings pass to'secure the holder to the deck of the ship or boat, and a two-part flanged collar, 13, having its halves fastened together by suitable bolts, 1),

passed through the flanges b, so as to clamp the collar B firmly and immovably upon the post 0 of the vessel-rudderD. The bed-plate A and collar B are tongued and grooved to gether, as shown clearly in Figs. 2 and 3, in which the tongue E is shown as formed upon the lower edge of the collar 13, and entering a groove, F, in the top edge or face of the bed plate, which is the preferred arrangement but the tongue may be formed on the bed-pla-te (No model.)

and the groove in the collar, if desired, as either construction will permit the collar B to turn freely in and be guided by the bed-plate A as the collar is swung horizontally in turning the rudder D from side to side in steering the vessel. I make the hole A through the bed-plate A larger than the hole through the collar 13, so that the rudder-post C, will not rub and ehafe or wear against the bed-plate, as will be seen in Fig. 3.

In applying my improvement,the rudder D is stepped or pivoted at the lower end in the shoe G, and the bed-plate A is placed around the rudder-post O and secured firmly to the vessels upper deck,or to any suitable support below the deck to accommodate the position of the steering-gear, and the collar Bis clamped to the post 0 and seated on or in the bed-plate A, with the tongue-and-groove joint fitted closely together and water-tight, so that all leakage into the vessel from around the rudder-post will be prevented. Any approved chock-block, H, is then applied on the vessels stern, against which block a shoulder on the rudder may rise to prevent the rudder from lifting out of its bearings in the shoe G or other support, which may or may not be braced by an outboard strut or hanger, I, as desired. Any suitable contrivanoes may be used to give the rudder 1) its lower end bearing, and to pre vent it from rising therefrom. The bed-plate 'A and collarB may each be formed in one or more pieces; but the construction shown is preferred.

It is evident that with my improved holder and support applied the rudder cannot break loose, and will be held to the vessel even if the shoe G be carried away, and the rudder-post will be held by the-tongue-and-groove joint of thebed-piece and collar, so as to work smoothly and freely at all times, and the weight of the rudder may be wholly or mainly carried by the bed-piece and collar A B to relieve the shoe G of downward strain.

If desired, an iron band or strap may be fitted loosely around the post 0 above the collar B,

and to be held to the bed-plate A or the vessels deck by bolts passed through arms of the band, and so that the latter may aid block H in preventing a rise of the rudder; or this upper band or strap may be used instead of the block H, if preferred.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the rudder-post O and its fixed collar B, of the bed-plate A,

. fixed to the vessel, tongued and grooved to the collar to enable the collar to turn upon it, and having an aperture, A, of such diameter as to isolate said plate or support from the rudderpost, substantially as and for the purpose set forth.

'2. The combination, with the rudder-post O and its fixed collar B, of the bed-plate A, fixed to the vessel, and tongued and grooved to the collar to enable the collar to turn upon it, said plate also having an aperture, A, of

such diameter as to isolate it from'the rudderpost, and the collar having a flange covering the upper surface of the plate, substantially as and for the purpose set forth.

3. The combination of the rudder-post O, collar B, fixed to the latter, the bed-plate A, fixed to the vessel, and tongued and grooved to the plate to enable the collar to turn upon it, said plate having an aperture, A, of such diameter as to isolate it from the rudder-post, the shoe G, and block H, substantially as and for the purpose set forth.
